"What's 'The Bachelorette' without a train wreck?" he told OnTheRedCarpet.com at the premiere of the Disney-Pixar film "Brave." "As things get more and more serious and Emily [Maynard] starts falling in love with more than one guy, the guys are all falling for her - it gets tougher and tougher for her to kind of have to do what she needs to do."

Harrison went on to explain how this season is a lot less drama, and a lot more heart.

"Honestly, in this season, it's not as much of the 'Oh my gosh, train wreck,' where you're trying to look through your fingers cause you don't want to see it," Harrison continued. "It really is more of a beautiful train wreck, it's more just heartbreaking where, again, Emily is falling for these guys and then she has to do what she doesn't want to do, which is let somebody go. It's really not that kind of salacious craziness that you've seen with some of these villains. It's a lot more serious and heartfelt."

Maynard, who is the first single mother to star on the show, won the previous 15th season of "The Bachelor" but later split with its star, Brad Womack.
